I'm just backing Clink up, here ...
Tecademics was created by Chris Record. I've known him for a while. Great dude, real as a heart attack, and someone who takes action on a grand scale.
Chris worked his way up from broke and nearly-foreclosed to kajillions in a few short years. He's put millions into this program, which is premised on his putting academic experts together with e-commerce entrepreneurs and creating marketing courses for various niches. They're designed for both corporate clients and individuals.
He offers great training and keeps it low- or no cost to make it easier for entry-level people to get involved. I can't speak highly enough for what he does and how he does it.
